Spring Security 基于数据库的认证

介绍

之前使用的全是基于内存的认证,这里使用基于数据库的认证。

设计数据表

这里设计数据表

创建项目

这里使用Mybatis作为项目。

添加如下依赖

添加driud连接池依赖

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.9</version>
        </dependency>

完整的pom如下

配置数据库

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    username: root
    password: ABCcba20170607
    url: jdbc:mysql://cdb-1yfd1mlm.cd.tencentcdb.com:10056/test

创建对应的实体类

package com.example.demo.domain;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;

import java.util.ArrayList;
import java.util.Collection;
import java.util.List;

public class User implements UserDetails {
    private Integer id;
    private String username;
    private String password;
    private Boolean enabled;
    private Boolean locked;
    private List<Role> roles;


    @Override
    // 实体类和SpringSecurity转换
    public Collection<? extends GrantedAuthority> getAuthorities() {
        List<SimpleGrantedAuthority> authorities = new ArrayList<>();
        for (Role role : roles) {
            authorities.add(new SimpleGrantedAuthority(role.getName()));
        }
        return authorities;
    }

    @Override
    public String getPassword() {
        return null;
    }

    @Override
    public String getUsername() {
        return null;
    }

    @Override
    public boolean isAccountNonExpired() {
        return false;
    }

    @Override
    public boolean isAccountNonLocked() {
        return false;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return false;
    }

    @Override
    public boolean isEnabled() {
        return false;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Boolean getEnabled() {
        return enabled;
    }

    public void setEnabled(Boolean enabled) {
        this.enabled = enabled;
    }

    public Boolean getLocked() {
        return locked;
    }

    public void setLocked(Boolean locked) {
        this.locked = locked;
    }

    public List<Role> getRoles() {
        return roles;
    }

    public void setRoles(List<Role> roles) {
        this.roles = roles;
    }
}

package com.example.demo.domain;

public class Role {
    private Integer id;
    private String name;
    private String nameZh;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getNameZh() {
        return nameZh;
    }

    public void setNameZh(String nameZh) {
        this.nameZh = nameZh;
    }
}

创建UserService

package com.example.demo.mapper;

import com.example.demo.domain.Role;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Select;
import org.graalvm.compiler.nodeinfo.StructuralInput;
import org.springframework.security.core.userdetails.User;

import java.util.List;

@Mapper
public interface UserMapper {
    @Select("select * from user where username=#{username}")
    public User loadUserByUsername(String username);

    @Select("select * from role r, user_role ur where r.id = ur.rid and ur.uid = #{id}")
    public List<Role> getUserRoleByUid(Integer id);
}

配置Spring Security

package com.example.demo.config;

import com.example.demo.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Configurable;
import org.springframework.context.annotation.Bean;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;


@Configurable
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private UserService userService;

    @Bean
    PasswordEncoder passwordEncoder(){
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userService);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/admin/**").hasRole("admin")
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginProcessingUrl("/login").permitAll()
                .and()
                .csrf().disable();
    }
}

至此完成。
